Buddhist digital amulets mark Thai entry into crypto art craze

by Thanaporn Promyamyai and Dene-Hern Chen

"CryptoAmulets" is the latest venture to chase the NFT art craze, with founder Ekkaphong Khemthong sensing opportunity in Thailand's widespread practice of collecting talismans blessed by revered monks.

Karmic fortune has arrived to the digital art market, with a kaleidoscopic splash of colours and the face of a revered Thai monk offering portable Buddhist good luck charms to tech-savvy buyers.

Sales of non-fungible tokens (NFTs)—virtual images of anything from popular internet memes to original artwork—have swept the art world in recent months, with some fetching millions of dollars at major auction houses.

"CryptoAmulets" is the latest venture to chase the craze, with founder Ekkaphong Khemthong sensing opportunity in Thailand's widespread practice of collecting talismans blessed by revered monks.

"I am an amulet collector and I was thinking about how I could introduce amulets to foreigners and to the world," he told AFP.

Collecting amulets and other small religious trinkets is a popular pastime in Buddhist-majority Thailand, where the capital Bangkok has a market solely dedicated to the traders of these lucky objects.

Their value can rise thousands of dollars if blessed by a well-respected monk.

Despite being a digital format, Ekkapong wanted CryptoAmulets to have the same traditional ceremony as a physical piece, which is why he approached Luang Pu Heng, a highly regarded abbot from Thailand's northeast.

"I respect this monk and I would love the world to know about him—he is a symbol of good fortune in business," he said.

Authentic and blessed

Luang Pu Heng last month presided over a ceremony to bless physical replicas of the digital amulets, which show a serene image of his face.

He splashed holy water onto his own visage as his saffron-robed disciples chanted and scattered yellow petals on the altar where the portraits were mounted.

One challenge was trying to explain the concept of NFTs to the 95-year-old abbot, who assumed he would be blessing physical amulets.

"It's very hard so we just tried to simplify it," said Singaporean developer Daye Chan.

"We said to him that it's like blessing the photos."

Transforming amulets into crypto art also means the usual questions of authenticity plaguing a talisman sold in a market are eliminated, he added

"There are so many amulets being mass produced... All the records could be lost and these physical items can be easily counterfeited," Chan said.

The value of Buddhist amulets and other religious trinkets can rise thousands of dollars if blessed by a well-respected monk.

NFTs use blockchain technology—an unalterable digital ledger—to record all transactions from the the moment of their creation.

"For our amulet, even a hundred years later, they can still check back the record to see what the blockchain is," Chan said.

But founder Ekkaphong would not be drawn on the karmic effectiveness of digital amulets, compared to their real-life counterparts.

"They are different," he said.

'Lucky experiences'

On the CryptoAmulets website online gallery, different inscriptions are written in Thai—"rich", "lucky" or "fortunate", for instance—around each of the tokens.

They are priced on a tiered system in ethereum, the world's second-largest cryptocurrency after bitcoin, and are currently selling for between $46 and $1,840.

Sales have been slow ahead of Sunday's purchase deadline, with only 1,500 tokens sold out of the 8,000 available, and with Thais making up most of the buyers.

Thai chef Theerapong Lertsongkram said he bought a CryptoAmulet because of his reverence for objects blessed by Luang Pu Heng, which he says have brought him good fortune.

"I have had several lucky experiences such as winning small lottery prizes... or being promoted on my job," said Theerapong, who works in a Stockholm restaurant.

"I did not know anything about NFTs before, but I made the decision to buy it as I respect Luang Pu Heng so much," he told AFP.

But fellow collector Wasan Sukjit—who adorns the interior of his taxi with rare amulets—has a harder time with the concept.

"Amulets need to be something physical, something people can hold," he scoffed.

"I prefer the ones I can hang on my neck."

NASA grapples with Hubble Telescope's most serious problem in years

ORLANDO, Fla., July 12 (UPI) -- NASA's Hubble Space Telescope is broken and the agency is struggling to understand the workhorse observatory's most serious problem in more than a decade.

Hubble stopped working suddenly June 13 while astronomers were using the 31-year-old telescope to examine pulsating stars 200 million miles away

NASA is trying to understand what went wrong on the orbiting telescope, without which hundreds of astronomy investigations had to be put on hold or canceled. At stake are efforts to understand galaxies, comets, stars, exoplanets and the entire universe.

Engineers have tried to restart the $1.5 billion telescope, which is about 43 feet long -- the length of a typical school bus -- and was named for astronomer Edwin Powell Hubble, who made a number of important discoveries before he died in 1953.

The team is preparing techniques to switch on secondary regulators that control data and power, NASA's astrophysics director Paul Hertz said in an interview. A failed piece of hardware on those regulators is the likely culprit, he said.

"Pretty much everything on Hubble, with some exceptions, is fully redundant, meaning there is a backup if something fails," Hertz said. "We can't say for sure exactly what is wrong, but we think it's a failure on a component that we're trying to isolate."

He said a solution is "likely," but he acknowledged there's a small possibility a fix from Earth isn't possible.

A team of about a dozen people at NASA's Goddard Space Flight Center in Maryland will now test procedures to safely turn on backup components, which Hertz said is complicated due the remote nature of the work and Hubble's suite of delicate high-tech instruments.

NASA does not have a spacecraft designed to service Hubble, which was deployed by space shuttle Discovery in 1990, Hertz said. The telescope orbits the Earth about 340 miles high, or roughly 80 miles higher than the International Space Station.

NASA performed a similar fix to Hubble in 2008 by switching on backup components. Then, in 2009, astronauts installed new backup equipment on a final shuttle trip.

Because the exact nature of the problem isn't known,, the agency cannot predict how long a fix will take. While some astronomy can be accomplished by other telescopes, Hubble is unique. It can make clear observations up to 15 billion light years away, farther than any other orbiting observatory.

NASA has hoped that Hubble would work in tandem with the James Webb Space Telescope, due to be launched from Florida's Kennedy Space Center in November.

The agency describes the new, more powerful telescope as a successor, not a replacement, for Hubble. That's because Hubble sees in optical light, while the James Webb telescope will see the universe in infrared light and be able to look a few hundred million light years farther than Hubble.

Hubble has enabled ground-breaking astronomy, astrophysicist Adam Reiss said.

"We were in the middle of observations of pulsating stars when it stopped working," Reiss said. He is a professor of space studies at Johns Hopkins University in Baltimore.

"It was obviously concerning but we are confident NASA will get it working again," he said. "Hubble's kind of a cat with nine lives, so to speak."

Hubble's accomplishments include observations of supernovae that allowed Reiss and Australian physicist Brian P. Schmidt to describe the expansion of the universe, work for which they were awarded a Nobel Prize.

"Hubble was absolutely critical in making some of those measurements," Reiss said. "It is sort of irreplaceable, and we're really hopeful that we'll get it back."

Canceled projects that may be rescheduled include observations of young stars, studies of galaxy centers that were to occur every other day for six months to determine variations in light and observations of the comet 288P to determine if it is a triple comet, NASA spokeswoman Alise Fischer said.

STORY HIGHLIGHTS

In addition to coffee, increasing intake of vegetables and decreasing consumption of processed meat can also help in reducing risk of coronavirus

If you are a coffee lover, scientists may have good news for you. A study has revealed that drinking a cup of coffee per day may reduce the chances of contracting coronavirus.

A study conducted by researchers from the Northwestern University has revealed that people who consume one or more cups of coffee per day have nearly 10 per cent less chance of getting infected by the deadly coronavirus, in comparison to those who are not consuming coffee at all.

"Coffee consumption favourably correlates with inflammatory biomarkers such as CRP, interleukin-6 (IL-6), and tumour necrosis factor I (TNF-I), which are also associated with Covid-19 severity and mortality," the study read.

It further added, "Coffee consumption has also been associated with lower risk of pneumonia in elderly. Taken together, an immunoprotective effect of coffee against Covid-19 is plausible and merits further investigation."

The result has been declared after analysing records of 40,000 British adults in the UK Biobank. The scientists studied the link between diet factors such as daily consumption of coffee, oily fish, processed meat, green vegetables, fresh fruit, red meat, etc and Covid.

It was also observed that consuming less processed meat and more vegetables could also cut down the chance of getting infected by COVID-19. Scientists revealed that consumption of at least 0.67 servings of vegetables (except potatoes) could help in reducing the risk of infection.

"Our results support the hypothesis that nutritional factors may influence distinct aspects of the immune system, hence susceptibility to COVID-19. Encouraging adherence to certain nutritional behaviours (eg, increasing vegetable intake and reducing processed meat intake) may be an additional tool to existing COVID-19 protection guidelines to limit the spread of this virus," said the researchers.

"Although these findings warrant independent confirmation, adherence to certain dietary behaviours may be an additional tool to existing COVID-19 protection guidelines to limit the spread of this virus," they added.

Confederate statues removed from Charlottesville parks

July 10 (UPI) -- Confederate statues of Robert E. Lee and Thomas "Stonewall" Jackson at the center of 2017 protests turned deadly were removed Saturday from city parks in Charlottesville, Va.

The bronze statues at the center of a "Unite the Right" rally on Aug. 12, 2017, that left Heather Heyer, 32, dead after James Fields drove his car into a crowd of counter-protesters, were removed from public property as reporters watched and observers cheered.

Cheers rang out as the Lee statue was lifted from its pedestal in Market Street Park shortly after 8 a.m., secured onto a large flatbed and driven away from the park a half hour later.

Crews later repeated the removal process with the Jackson statue in Court Square Park, and crowd similarly cheered as it was removed from its pedestal shortly before 10 a.m.

RELATED House votes to remove Confederate statues from Capitol

"(Removing the statues) is one step closer to the goal of helping Charlottesville, Virginia, and America grapple with its sin of being willing to destroy Black people for economic gains," Charlottesville Mayor Nikuyah Walker said shortly before the Lee statue was removed, CNN reported.

The statues will be placed in storage and the stone base pedestals were left in place to be removed at a later date.

"During the past month, the city has solicited for expressions of interest from any museum, historical society, government or military battlefield interested in acquiring the statues, or either of them, for relocation and placement," the city said in a statement Friday.

The Charlottesville City Council voted on June 7 to remove the statues after a court battle that dragged out more than three years.

The white supremacist rally in which Heyer was killed and 19 others injured occurred after the council first voted to remove the statues in February 2017.

A circuit judge ruled shortly after the rally that state law barred the statutes' removal, according to court documents

Supreme Court of Virginia, however, overturned that decision in April 2021, ruling that the state law, which was enacted in 1997, "had no retroactive applicability."

Sea-level rise may worsen existing Bay Area inequities

Rather than waiting for certainty in sea-level rise projections, policymakers can plan now for future coastal flooding by addressing existing inequities among the most vulnerable communities in flood zones, according to Stanford research.

Using a methodology that incorporates socioeconomic data on neighborhood groups of about 1,500 people, scientists found that several coastal communities in San Mateo County, California - including half the households in East Palo Alto - are at risk of financial instability from existing social factors or anticipated flooding through 2060. Even with coverage from flood insurance, these residents would not be able to pay for damages from flooding, which could lead to homelessness or bankruptcy among people who are essential to the diversity and economic function of urban areas. The paper was published in the journal Earth's Future on July 12.

"These are workers that make a city run, they're the heart and soul of an urban operation. If you displace a significant majority too far outside the urban area, the functionality of that city crumbles," said senior co-author Jenny Suckale, an assistant professor of geophysics at Stanford's School of Earth, Energy & Environmental Sciences (Stanford Earth). "How can we make sure that we provide a future to these communities that does not entail their disintegration?"

Flood damage estimates are typically calculated by civil engineers in terms of monetary damage to physical structures. With their new model, called the Stanford Urban Risk Framework (SURF), the researchers bring a human-centered approach to risk assessment that focuses on the residents most likely to lose their livelihoods when water inundates their homes. While every household within the projected flood plain will be burdened by flood damages, the socioeconomic context determines how harmful the costs will be. In several coastal communities in San Mateo County, more than 50 percent of households will be facing financial instability.

"If you just look at the dollar amount, you're missing one major component of the problem," Suckale said. "What might be a nuisance in some communities is life-changing in other communities - it's really about the proximity to a tipping point."

The researchers determined which communities are near a fiscal tipping point by calculating their social risk, or financial instability, a metric intended to complement existing assessments of monetary risk from hazards. They overlaid coastal flood maps and building footprints with structural information, incorporated projected annual damages from sea-level rise and estimated household discretionary income based on labor and economic data in order to calculate losses based on census block groups - geographical units used by the U.S. Census Bureau to publish demographic estimates.

"It was surprising to see in the data how much more lower-income households were affected as a proportion of their income and just how unsustainable it is for those types of households to absorb these costs," said lead study author Avery Bick, a PhD student with the Norwegian Institute for Nature Research who worked on the project as a graduate student at Stanford.

Despite uncertainty over the magnitude of future climate change, researchers agree that sea-level rise will increase coastal flooding - a hazard that residents from Foster City to East Palo Alto have already experienced in the past several decades. Many of the neighborhoods with the highest social risk comprise single-parent households and are more racially diverse than the San Mateo County average, according to the research.

"Climate change isn't just about getting hotter or sea-level rise - it's literally going to change the entire fabric of society, especially if we continue to ignore it," Bick said. "This gave me a sense of how vulnerable the social fabric is to change and how we need to be proactive; otherwise it will change in favor of those that have more resources."

The researchers collaborated with local stakeholders to develop an equitable approach to sea-level rise adaptation planning. Through conversations with organizations like the San Mateo County Office of Sustainability and the U.S. Army Corps of Engineers, as well as community-based groups like Climate Resilient Communities, El Concilio and North Fair Oaks Community Alliance, they learned that what was missing from the climate discourse was a framing of dollar-amount damage relative to what people are able to pay. The team's approach involved a mind shift, from the amount of money you lose to the value of the goods and services you can no longer purchase because of the disaster, said study co-author Derek Ouyang, a geophysics lecturer at Stanford Earth.

"Any investment now can be directly linked to the resilience that prepares communities for future climate hazards, whatever they are," Ouyang said.

Because San Mateo County includes both very wealthy and low-income residents, averaging the costs of flooding in comparison to the income of its residents at the county scale "makes it look like you don't have much of a problem," Suckale said. By assessing impacts at a smaller scale, however, the researchers were able to highlight the areas of concern in a way that is more directly useful to policymakers.

The co-authors hope this new quantitative method for assessing social risk on a census block group scale can be used in other regions vulnerable to coastal flooding or for understanding different climate hazards through an equitable lens.

"I think it's useful to have a metric of social risk that is entirely agnostic of the actual hazard, because then we can just improve the ability of the household to absorb the disruption, no matter what it is," Suckale said.

Heat pumps on the rise after Minnesota passes new energy law

by Frank Jossie Of Energy News Network

Air source heat pumps are on the rise in rural Minnesota and utility officials expect momentum to grow as a result of the state's new energy conservation law.

A year-and-a-half-old collaboration between the nonprofit Center for Energy and Environment and five outstate Minnesota utilities is aiming to make heat pumps mainstream by the end of the decade by offering training and other support to contractors, as well as rebate referrals and information to consumers.

The Minnesota Air Source Heat Pump Collaborative has identified rebates available to customers in nearly every utility territory ranging from $200 to $2,000. The number of rebates awarded by its members more than doubled to 3,107 in 2020 compared to 1,356 in 2019.

Utility officials expect those numbers to keep climbing, in part due to the state's recently signed Energy Conservation and Optimization (ECO) Act. The legislation frees up utilities to make comparisons between propane and other fuels when marketing heat pumps. In addition, it allows utilities to count energy savings from fuel-switching toward their energy conservation targets.

"The single biggest idea here from a policy standpoint is this bill says if you're reducing total energy, you're doing energy efficiency even if that means electricity use goes up," said Darrick Moe, executive director of the Minnesota Rural Electric Association. "The law pushes past the fuel-switching prohibition."

Gas and electric utilities are now essentially allowed to poach each others' customers, though the economics suggest most conversions will flow toward electrification. Utilities are also capped on the amount of energy savings they can claim through fuel-switching, which can't exceed 0.55% of the requirement.

The fuel-switching change applies statewide, but there's more interest in Greater Minnesota, where many customers rely on relatively expensive propane heating and the switch to heat pumps can produce quick cost and energy savings.

"It's kind of a no-brainer in houses with propane furnaces," said Ben Schoenbauer, senior research engineer at the Center for Energy and Environment, which has conducted a wide range of research on heat pumps that shows they can save customers 30% to 55% when they replace propane or electric resistance heat.

The Air Source Heat Pump Collaborative emerged after a 2018 study by the Center for Energy and Environment showed the high potential of heat pumps to produce energy savings this decade, according to program development manager Emily McPherson. Members include Minnesota Power, Southern Minnesota Municipal Power, Great River Energy, Missouri River Energy Services, and Otter Tail Power.

The recent rise of heat pumps in those territories is a result of more generous rebates, as well as supply chain problems in the air conditioning sector and more people working at home doing improvement projects. McPherson said heat pumps continue to be popular in rural areas and she hopes the ECO Act "will help continue the momentum."

Christopher P. Schoenherr, government relations and chief external affairs officer for Southern Minnesota Municipal Power Agency, said the key to growing the market will be educating contractors. That's why the collaborative is offering free online training to help HVAC professionals learn the technology.

"We're already seeing the interest start to build," he said. "Outreach to contractors and other trade allies is going to be the key to really making this take off because they're the folks that are going to be talking directly to the customer."

Jeff Haase, manager of member services at Great River Energy, said the entry point for heat pumps comes for many homeowners when they are looking for a new air conditioner. Then they discover a heat pump can both cool and heat a home for most of the year. "You're looking at it through the lens of the furnace, but you're also looking at it through the lens of the air conditioner," he said.

In northern Minnesota, homeowners could see great value in using heat pumps for cooling on the few hot summer days in that part of the state, and also use it to heat their homes during the fall and spring, which coincides with when wind energy is widely available. Customers generally need just one propane tank to get through winter, and they can buy it off-season when prices are cheaper than January or February.

The heating-cooling combination led Mark Nelson to replace the propane heating and cooling system in his Pine City home with a heat pump and a new propane furnace. He used a rebate to reduce the cost of the technology and subscribed to a heat pump electricity rate offered by East Central, where he works as the manager of government and business relations.

The heat pump keeps his home warm until temperatures drop below 25 degrees Fahrenheit, when the propane furnace starts up. His fuel consumption dropped annually from 1,200 gallons to 500 gallons. The electricity rate and lower propane use save $300 to $400 yearly and the new system runs quieter, saves money and provides as much comfort, "if not more," he said, than the old system.

Newer, more expensive cold climate models can heat well below zero while mini-split air source heat pumps, popular for air conditioning, heat down to 25 or 30 degrees. While the cold climate air source heat pump technology manages subzero temperatures, the appliances generally cost several thousand dollars more than fossil fuel furnaces.

Moe, of the rural utilities association, said utilities that already have heat pump rebate programs may decide to increase those incentives now that they can count the savings toward their energy conservation targets. He sees a likely boost in air source heat pump sales rather than a giant leap, though.

"I'm not saying a year from now everybody's going to be using heat pumps, because the reality is it is kind of a transition that's already happening, and now the program's better equipped to be a tool for that," he said.

The replacement of propane and natural gas with heat pumps only delivers a 5% decline in carbon emissions. As the state's utilities transition to cleaner power, though, the carbon reduction will increase.

"Just looking over what the utilities plan to do in the next 10 to 25 years with (closing) coal plants it's going to be a big, a big win," Schoenbauer said. "Those changes will happen within the lifetime of a heat pump installed today."

Carbon heat pumps smart option for hotels in cold climates

Creating smarter, healthier transportation systems

by Tim Peeler, North Carolina State University

NC State assistant civil engineering professor Eleni Bardaka grew up in Athens, Greece, watching her mom take public transportation to work every day and eventually finding her own personal independence using multiple options to get around the modern version of the ancient city.

Throughout her educational career—Bardaka earned a civil engineering degree from the National Technical University of Athens, a master's degree in economics from Purdue and a Ph.D. in civil engineering from Purdue—she has devoted her time to developing alternative transportation systems that don't necessarily rely on the modes of transportation that evolved in the United States following World War II.

For three-quarters of a century, U.S. residents have been untethered on the road with their personal vehicles. How, though, do you unclog the traffic those vehicles create, sometimes like a cholesterol-filled artery? How do you get people around town and from place to place, not only to relieve traffic but also to get people moving on their own?

Bardaka came to NC State from Purdue in 2017 to tackle those issues, particularly in her undergraduate/graduate class Transportation Systems Analysis (Civil Engineering 401/501), where she includes alternatives to just widening a road or putting in an additional lane. Along with her undergraduate class, Introduction to Sustainable Infrastructure (CE 297), Bardaka is cognizant that transportation planning has a huge impact on a community's physical, mental and sustainable well-being.

In a country where even most large and midsize cities, like those in North Carolina, rely on personal vehicles, transportation systems are built more with suburban development in mind, not public transportation.

"It wastes a lot of resources and creates a lot of traffic," Bardaka says. "So we have to get smarter with how we build our systems."

The stigma of public transportation

One of the biggest ways to tackle the issue is to remove the stigma of public transportation, something that was not part of her Greek background. In the U.S., however, public mass transportation planning is often devoted to large interstate projects, loops and bypasses instead of light rail or other systems that move larger numbers of people at one time.

And those roadways can create division, even while they offer solutions.

"We talk a lot about how interconnected the transportation system and societal systems are," Bardaka says. "How do we make decisions about how we get somewhere? In terms of building something, investing in something, these decisions affect communities, sometimes in a positive way. But we also have a lot of examples where these decisions are also segregating, dividing and harming communities."

One of her recent students, Adam Schmidt, spent the better part of the spring working on a project that looked at how the gentrification of uptown Charlotte followed the city's installation of its Lynx light rail system, a 19-mile, 26-stop line that opened in 2007.

"What I liked from the beginning is that this is the only transportation class I had ever taken that wasn't specifically focused on cars," Schmidt says. "This class is about how people decide how they get to work or go shopping or things like that."

It was foreign territory to Schmidt, who grew up outside of Greenville, North Carolina, where public transportation was about as scarce as authentic baklava.

"It does start with the stigma that gets ingrained early," Schmidt says. "What makes people want to ride the bus and take public transportation? For me, the class provided a window into how people make those decisions."

New ways to travel

And there is a specific wellness aspect that comes with that, as people learn new ways to travel and commute. Bardaka concedes that hers is not at all a design course, but a vehicle for thought about new ways to move.

"I mostly educate the students about how to get a broader perspective on the impacts of everything we do in transportation," she says. "I think there are a lot of connections on the different perspectives of wellness, like physical wellness, social and community wellness. So there is a behavioral component in which we consider how to design infrastructure, how to design municipal and state policies and how we place infrastructure components.

"As we do those things, it will lead to healthier communities. Future engineers have the responsibility to consider the wellness of individuals and communities."

Hong Kong's urban farms sprout gardens in the sky

by Celia Cazale

More than 60 urban farms have sprouted across space-starved Hong Kong since 2015—on decommissioned helipads, shopping mall rooftops and public terraces—thanks to initiatives like Rooftop Republic.

With their heads in the clouds and their hands in the soil, a group of office workers are busy harvesting the fruits of their labour on the roof of a Hong Kong skyscraper.

Invisible to those below, a sprawling garden of radishes, carrots and rhubarb is flourishing at the top of the 150-metre tall Bank of America tower, a stark and colourful contrast to the monotone shades of concrete, steel and glass of the city's financial district.

The farm is among more than 60 that have sprouted across the space-starved city since 2015—on decommissioned helipads, shopping mall rooftops and public terraces—thanks to initiatives like Rooftop Republic, a local social enterprise which promotes urban farming.

Cofounder Andrew Tsui sees the rooftop farms as a way for people to reconnect with how sustainable food can be produced in what he calls the current "instant-noodle city lifestyle" that sees so much waste.

"What we are looking at is really how to identify underutilised spaces among the city and mobilise the citizens, the people, to learn about food," the 43-year-old told AFP during a blustery site inspection of the skyscraper's garden.

Tsui believes Hong Kongers need to re-establish a relationship with what they eat that has been broken "since we started outsourcing our food and relying so much on industrialised production."

Andrew Tsui of Rooftop Republic sees the farms as a way for people to reconnect with how sustainable food can be produced in what he calls the current "instant-noodle city lifestyle" that produces so much waste.

Piles of food waste

According to government statistics, Hong Kong throws out some 3,500 tonnes of food waste a day—the equivalent weight of 250 double-decker buses. Less than a quarter is recycled.

And around 90 percent of the food eaten by the city's 7.5 million inhabitants is imported, mostly from mainland China.

But while Hong Kong is one of the most densely packed places on earth, there is still considerable space to grow food locally.

Tsui said some seven million square metres of farmable area is currently cultivated. But more than six million square metres on the city's rooftops remain unused.

"So we could have the potential of doubling the supply of land for growing food," he said.

"The challenge for us is to design urban farming as a lifestyle to integrate into our daily life," he added. "And the first step for that, of course, is to be accessible."

Tsui believes Hong Kongers need to re-establish a relationship with what they eat that has been broken "since we started outsourcing our food and relying so much on industrialised production"

To incorporate urban farms into the blueprints for office buildings, Rooftop Republic closely collaborates with architects, developers and property managers.

America garden, financed by property consultancy giant JLL, Singaporean banking giant DBS has partnered with Rooftop Republic to set up an academy that runs workshops for beginners as well as professional cou

"In Hong Kong, most of the people focus on the commercial value of the properties. But we want to promote the concept of sustainability," said Eric Lau, the group's senior director of property management.

New skills

Urban farmers say the projects also help build community spirit among those who cultivate the crops.

After retiring from the public service, Lai Yee-man said she turned to farming to connect with nature and her neighbours.

The 60-year-old initially learned techniques and tricks from professionals to develop her farming plot in the New Territories region of Hong Kong—a rural area close to the border with mainland China.

But now she is passing on her knowledge to fellow residents working the Sky Garden, a 1,200 square-metre facility on top of a mall.

There residents cultivate edible flowers and fruit trees and can attend lifestyle classes like mindful gardening.

"People attach greater importance to their health now, they will buy organic food," said Lai.

"Here, we teach them not to waste... and to cherish their food," she explained, adding that the majority of what the mall farm grows goes to local food banks.

Tsui recognises that few young Hong Kongers currently have an interest in learning how to grow food.

But younger people are often concerned about the environment and climate change, so the opportunity to generate enthusiasm is there for the taking.

"If coding is the skill set to learn for the 21st century, growing your own food is a necessary new skill that we all need to learn to ensure a regenerative and green planet," he said.
